Patent ES-436946-A1 (ES)
Title: Apparatus and method for measuring the rate of change of thickness of dielectric members
IPC: B07C5/12
Filed: 1975-04-25
Abstract: Apparatus for detecting the presence of relatively narrow, thin sections in the sidewall of glass containers and rejecting those containers which exhibit such narrow, thin sections. A radio frequency source coupled to a transmitting antenna positioned adjacent the container establishes a radio frequency field extending through the wall of the glass container. The wall of the container is moved relative to a receiving probe. The instantaneous magnitude of the field received by the probe provides an indication of the thickness of the container sidewall. The signal received is amplified and the first derivative of the voltage with respect to time is taken. The rate of change of the voltage is a direct indication of the change in thickness of successive sections of the container sidewall being gauged. Those containers which exhibit a rate of change of voltage with respect to time above a preset level are rejected as being defective.

Title: Analogues of prostanoic acids and process for preparing them
IPC: A61K31/557
Filed: 1976-10-30
Abstract: Novel analogues of prostanoic acids, which have the accompanying formula I, in which the symbols R1 to R3 have the meaning given in Patent Claim 1, are prepared by removing the tetrahydropyranyl ether protective group and the ketal grouping simultaneously or successively from an appropriately substituted 3-tetrahydropyranyloxy- 1,5-dioxaspiro compound. The corresponding compounds in which, instead of the keto group in the cyclopentyl radical, hydrogen and a hydroxy group are present, are obtained by reduction with a complex metal hydride. The compounds can then be converted into their physiologically tolerable salts or esters. The compounds are distinguished, even in the form of their epimer mixtures, by a good general spasmolytic, in particular bronchodilatory, action. They additionally have a hypotensive action and can also be employed in some cases in gastrointestinal disorders.

Title: Vacuum control for sheet applicator machines
IPC: B65H3/08
Filed: 1979-01-19
Abstract: A sheet applicator particularly suitable for bag-making machines comprises suction members controlled by a three-way valve to apply a vacuum to them at a sheet withdrawing station and atmospheric pressure when they have been reciprocated to a sheet releasing station. The valve comprises a first chamber communicating with atmospheric pressure and a second chamber of larger diameter than the first communicating with a source of vacuum, the chambers being alternately connected to the suction members by a valve plate displaceable between the chambers to close one of them and open the other. A spring acts on the valve plate with a force insufficient to displace it when it is closing the said second chamber but sufficient to hold it closed when it is closing the first chamber. Actual displacement of the valve plate is effected by a valve rod therefor striking abutments at the sheet withdrawing and sheet releasing stations.

Title: Method of feeding bodies to conveyor from continuous bodies and its device
IPC: B65G47/84
Filed: 1979-05-04
Abstract: In a transfer system of articles, esp. the outer boxes of matchboxes, to a conveyor the outer boxes are centred and moved along by a pair of endless belts which contact their sides. A synchronising device at the discharge end consists of two cam discs with cut-outs which grip behind the lagging wall of a box. The belt contact is slack enough to allow the belt to slide between the box movement cycles. The articles are thus first kept in a fast uniform motion, followed by their synchronised transfer to a processing conveyor.
